Nodosaurus ("knobbed lizard") was an herbivorous dinosaur from the Late Cretaceous, the fossils of which are established in North America. Three unfinished specimens have been exposed in Wyoming and Kansas, and no skulls. One of the first armored dinosaurs to be exposed in North America, Nodosaurus was named by O. Marsh in 1889.

Nodosaurus Dinosaur This nodosaurid ankylosaur was concerning 13 to 20 feet (four to six meters) long. It was an ornithischian dinosaur with bony dermal plates casing the top of its body. It may have had spikes the length of its side as well. It had four short legs, five-toed feet, a short neck, and a long, stiff, clubless tail. The head was thin, with a pointed snout, powerful jaws, and small teeth. It almost certainly ate soft plants, as it would be unable to chew tough, fibrous ones.

It is consideration that without a club on its tail, Nodosaurus was left with no much in terms of defense. When threatened, it almost certainly dropped to the ground so that only its armored back and sides were uncovered.

Dinosaurs Fossils

Dinosaur fossils have been known about for millennia, though their true nature was not recognized; the Chinese considered them to be dragon bones, while Europeans believed them to be the remains of giants and other creatures killed by the Great Flood.
